During an appearance on “The Tonight Show” on Wednesday (Sept. 11), Sheen opened up to host Jay Leno, jokingly referring to the series as “Anger Management 2.0” — “the reboot.”

“One of our primary character, Selma Blair, who played Kate, was written out because [the show] was not about our relationship, and the problem was too many people were still excited about the ‘Two and a Half [Men’] character and thought the ‘Anger Management’ character was a little dull,” Sheen, who was fired from CBS’ hit comedy two years ago, started.

“So, um, that is not the case anymore,” he added, referring to the idea that his character might be too boring. “Her character leaves, and I start circling the drain. So it’s really fun to watch and hella fun to play.”

Leno asked Sheen which moments from his life he drew from to play the drain circling. “It’s a mystery,” Sheen joked. “It just falls out of the sky. It’s amazing.”
